ceo-approve was bound to QANotes (notes required), so the panel's
one-click approve (posts {}) 422'd. The wrong fix is to waive notes —
that empties the audit record for a production merge. Instead require
substantive notes (>=20 chars, mirroring pass-qa) and make the panel
COLLECT them: a new CeoApproveDialog (mirrors the reject dialog) gates
the 'Approve & Merge' action, and the dashboard approval-queue enforces
the same before POSTing. The CEO sign-off note is now always captured.
